There are several tools available for doing this type of simulation, but the one that I have found to be the best all-around tool for real EMI PCB/System simulation is FLO-EMC from Flomerics. It is a time-domain field solver using the TLM method as its solution engine.=20 Hope this helps.

The tools should cover both low frequency and high frequency. Any of you know which company has this type of products? Ideal, the tool can accept board CAD files and system mechanical CAD files.=20 Thanks!
